Can they void this question? Both sets of solutions posted here have put the two conflicting answers.

NESA wouldn't put a purposefully incorrect answer (would they?) that being inclusive of 6.0, but using the intended rectangle solution overestimate it can't be A.

It does say "best estimate", but I don't think that grants an obviously incorrect solution by virtue of the question's setup.

I don't know if it was to make the answers look the same, that being the lower bound inclusive, upper bound non-inclusive, but still wouldn't really justify this.

cant remember exactly but the probability of the weight they gave us was smth like 0.025, then using empirical rule that turns into a probability of Z>2

Hey that was in standard! Also the quadratic was in standard

 

[tropics...]

tf

like harder than 2020/21 but easier than 2024/23 imo

guys, what would a raw 65 approx scale to?

no the answer is definitive, B. its impossible for f(1.1) to be >= 6.2 so A is not the answer. the true value of f(1.1) is in the interval of B.

Id say itll scrape a band 5, maybe 78-80

 

[Bob123d3gt41]

the questions and sol are out btw idk if you already have em

yeah i get that logic, but its equally as impossible for the answer to be 6.0 right? because the area from 1->1.1 under the curve is non zero. so you can't increases by a stationary amount?

i presume this was tywebb's logic behind the question. i do agree A is completely wrong.

yes (6.0, 6.2) is also correct but its not saying that f(1.1) could be anything in [6,6.2), its just asking which interval CAN it be in, hence the wording "INCLUDES"

81-83

fair i just thought it was odd they exclude the top bound and include the bottom bound where bout are not possible.

i think its pretty clearly B, because it cant go under 6 and it cant be 6
pretty rare for nesa to make a glaring mistake or to nullify a question

yeah makes sense. sucks cause I saw the question in terms of it being increasing and not including 6.0 instead of an area overestimate question, so I wasn't able to cross-check A.

where?

 

[HappyTheSkibidi]

Any idea what a raw 78-83 would scale to?
I genuinely spent 1 and a half hours on the last 5 questions and I was only able to get one of them

 

[MrMemer1234]

bruh thats not even my worst... i got eco and business right after back to back which means i gotta make the most of my time rn lol

ayy same

best of luck

 

[bigupsanky]

ayy same

best of luck

you too brother

im hoping a 90 this year last year a 76 scaled to 90

no frrr i spent so long on the last few qs

these are from prev years’ raw -> scaled marks

oh oops didn’t see that someone already replied
